Morrison's Rhyl in the aisle with gardening type stuff, 5 LED headlamps at £2.50!
comes complete with the required two 3volt batteries (flat 10p sized type)
(which if bought separately would set you back nearly £4 at Morrisons prices!)
white/flashing and red modes
casts a good light (only tried it indoors so far) and its a neat, small, lightweight unit.
Not quite sure I'd rely on it as my main light but it looks a great cheap back up light at a disposable price that takes up little space in the pocket.
Got carried away, had two...
and then the bargain Rolson Zillion candle power rechargeable handlamp at £8 next to them fell into my basket
Remind me, what was it I went in for? Oh yeah a cheap pizza.
